Might be looking to sell a complete 71 casting 340 engine and transmission. Was originally pulled from a wreck decades ago (more than 40 years). Engine is stuck. All accessories are original to this particular engine. Just wondering what the membership thinks it's worth ?? I have the air breather and exhaust manifold's for it but they are not original to this engine. The vin number decode as a 1972 and it's a forged steel crank.

Sold a 71 just like it a few years back without the k-frame, exhaust manifolds, and air cleaner for $2500 but it was not stuck. If I were you at least get it to turn over, oil it up and put a breaker bar on it... twocents

What's the number on the carb? the 71's were different than subsequent years and are more sought after wink

Had an aluminum intake and newer AFB, I would have kept the carb if it was a real 71... biggrin

The last “stuck” engine I had to rebuild needed .030 to clean up the rust pits. All it had was the carb off for about 20 years in Garland Texas. The more damp the conditions it’s stored in will determine the amount of rust. It could have had some water in a cly and that would be worse. A buyer is taking a big chance on that one. Pull the heads and have a look. I would not buy it at all until I could see the heads off and put a mic on it. It could be a $100 piece or a $2000 one. If it was .030 plus some rust, it’s not worth much for the block.

Can't recall the number off hand but it's not the 71 carb as you mentioned. The carb as well as all the other accessories are original to the engine. The carb still has the plastic covers over the idle mixture screws. I believe the engine has low mileage as everything appears to be original to this engine. Again it's a 71 casting for the block but everyone else including the vin number is 1972.

Other than their number , 1971 thermoquads are easily identified by their angled idle mixture screws.

All others were straight on like the ones on the posted pictures.

The adjustment screws aren't at an angle on that carb, it's not a 71 $$

Yes I agree it's not a 71 carb or are any other accessories. It's all date coded 1972 it's just the block that was cast in 1971 and it has a steel forged crank as opposed to the cast crankshaft that came out at some point. It was also removed from a 1972 vehicle.

If the block was cast in 1968 and then finally installed with 1970 #'s on it it is a 1970 motor.

Most everyone wants their items to be 1971 or before.

Blocks were cast and sometimes sat around for a while.

You seem to have a 1972 motor.

I agree that if you could get your 1972 motor to turn over then your chances of selling would be much better. Best of luck.

First and foremost I appreciate all input and I agree with your post. Now I listed it as a 1972 340 and 727 with a 1971 casting date which makes me believe that is why it has a steel crankshaft as opposed to the later cast crankshaft. I'm not trying to figure out what I have but what is the going price for a engine/trans that has been together since it was manufactured ???
Thanks again for all opinions.

I was toying with a stuck (from sitting) VW motor a few years ago. Pulled the plugs and filled the cylinders with transmission fluid. Every day or 2 I'd put some pressure on the crank nut, both directions. After a couple weeks it began to move. Worked it slowly from there and within a few days it spun freely.
I'm sure you know that it'll be worth more if you can get it to turn. twocents

I think Marvel Mystery Oil might work though.

It is good stuff. Will fix a ticking lifter etc. Works,as,air tool lube.
Sea foam Works on gas really good too for fuel system clean up.

The original poster wants a value for a 72 340.
I'd say that it being stuck makes the estimate more difficult, and it may scare some buyers (why folks suggest you free it up).
If it's still standard bore I think that adds value.
A body V8 K frames are worth a few bills these days
The carb can be worth about $300 as a core to someone seeking that exact #.
For reference I paid five or six hundred bucks for the last 340 block I bought 2 years ago (standard bore).
A good complete 340 long block with motor mounts, valve covers, early alternator, oil filter adapter, I'd say these days maybe up to $1200-1500
